Claims

[Scope of utility model registration request]

A cassette holder is arranged horizontally between a pair of left and right support plates, and the left and right ends of the connecting plate, which is arranged horizontally between the two support plates at the top of the cassette holder, are connected to the first fulcrum shaft on both the support plates. The connecting plate is rotatably supported through the cassette holder, and the positions at both left and right ends of the connecting plate that are spaced rearward from the first fulcrum shaft are at both ends of the cassette holder in the left and right direction and at the central position in the front and back direction. The support plate is rotatably supported through a pair of left and right second fulcrum shafts, and is attached to the side surface of one of the support plates so as to be slidable in the front and back direction, and is slidable forward by a spring. The biased sliding plate is engaged with one of the left and right ends of the connecting plate, and this sliding plate is slid backward against the spring, thereby causing the connecting plate to move to the second position. The cassette holder is raised to a cassette insertion position by rotating upward about one fulcrum shaft, and after the disk cassette has been inserted into the cassette holder, the sliding plate is slid forward by the spring. The connecting plate is rotated downward about the first fulcrum shaft to lower the cassette holder from the cassette insertion position to the cassette mounting position, and the four corners of the disc cassette are engaged with the four positioning pins. In the disk cassette mounting device configured to position the disk cassette, an arm extending from the pivot portion of the first fulcrum shaft is integrally provided at one end of the connecting plate, and the length of the arm is set as above. The separation distance of the second fulcrum shaft from the first fulcrum shaft is set to be equal to A forward sliding force is transmitted to the arm through the protrusion to urge the connecting plate to rotate downward about the first fulcrum shaft, and when the cassette holder has been completely lowered to the cassette mounting position. In addition, by keeping the protrusion in contact with the arm from behind by the spring, the cassette holder that has been lowered is further pressed downward by the spring force, and the spring force causes the cassette holder to be further pressed downward. A disk cassette mounting device characterized in that the disk cassette is positioned by pressing the four corners of the disk cassette onto the four positioning pins via the cassette holder.
